How to Change Batteries on Your MSA Sordin Supreme Pro X Electronic Earmuffs

PLEASE NOTE THE BATTERIES ARE INSTALLED WRONGLY IN THIS VIDEO. PUT THE FIRST BATTERY WITH THE NEGATIVE INTO THE HOLE INTO THE HOLE AND THE SECOND WITH POSITIVE TOWARDS THE HOLE. The MSA Sordin Supreme Pro X are excellent earmuffs. However the design on changing the AA batteries is not easy banging it until the second battery falls out. However with a 0.9mm allen key it is simple and not damaging your earmuffs. I have used this technique for 6 years of use.
